Abstract: ABSTRACT OF THE DISCLOSURE The invention provides a junction coupling for branching a flow of fluid from a pipe or conduit.  The junction coupling is essentially C-shaped and is dimen-sioned partly to surround such pipe or conduit.  Opposite limbs of the C-shaped member carry, on the one hand, an outlet duct and on the other hand means for securing the coupling in position on the pipe or conduit.  The outlet duct is alignable with an aperture in the conduit wall and adapted to receive a branch conduit. The dimen-sions of the C-shaped member are such that the coupling may be engaged over the pipe or conduit only at the location of the aperture therein.

Abstract: ABSTRACT A closure device for a port of a chamber especially the charging port of a plant for dry cooling coke, has upper and lower lids arranged to be capable of being opened and closed independently of each other, each lid being able to remain closed when the other lid is open.  This is achieved by providing sealing means around the opening of the chamber which cooperate with sealing means afforded by operating means arranged to open and close the inner lid.  The operating means also carry sealing means which cooperate with sealing means on a removable upper lid and with sealing means on the charging means for example a coke hopper.

Abstract: IMPROVED EXCESS-GROWTH CONTROL SYSTEM FOR FLUIDIZED-BED REACTOR     ABSTRACT OF DISCLOSURE     A control system to prevent the accumulation of excessive cellular material in a fluidized-bed reactor wherein a waste liquid to be processed is conducted upwardly at a velocity con-ducive to fluidization through a bed of particles which function as a carrier for the growth of the material.  The system includes a separator column whose low end section extends toward the fluidized bed and whose high end section extends above a head of liquid effluent which lies on the bed, or is sealed and located below the surface of liquid effluent, the diameter of the high end section being greater than that of the low end section.  In the course of reactor operation, the cellular material on the particles continues to grow, causing the bed to expand until its level reaches a point indicative of excessive growth.  This point is sensed to activate an agitator arrangement which effects shearing of the excess cellular material from the particles to produce in the separator column a mixture of sheared material and partially stripped carrier particles.  The separator column is provided with a draw-off port somewhat below the surface of the effluent head, the exit flow rate at the draw-off port being ad-justed so that the resultant upward flow velocity in the separa-tor column is lower than the settling velocity of the carrier particles in the mixture but higher than that of the sheared material.  As a consequence, the sheared material is washed away through the draw-off port, whereas the partially stripped carrier particles fall back into the fluidized bed.

Abstract: ABSTRACT OF THE DISCLOSURE           A navigation channel is made in the ice covering the surface of a waterway by propelling a vessel so that its bow breaks the ice to form a channel having a width of the beam of the ship and an auxiliary channel is similarly formed at each side of the ship in rear of its bow to provide leeway for the ship to turn.  As the ship is turned, the auxiliary channel is enlarged by breaking the ice on the edge of the auxiliary channel toward the stern of the ship to give it greater leeway to turn.  The auxiliary channel may be broken out by fin means projecting from the side of the ship effective to exert forward, upward and outward force against the ice blanket to break pieces from it.
